5-Speed Manual in '94 Bonneville?
It'* all here. And keep in mind with the L67/Gertrag setup, don't readily compare a Fiero to a Bonneville. There'* a wee bit 'O weight difference. Makes quite an impact on the clutch setup. 
And then you have to delete lines of code from the PCM for the old trans that went in the junk heap.

It'* just that.... the sportiness of shifting. Driving a manual can be a lot more fun, and I'm under the impression they're easier to work on than automatics. It is less convenient, but I'd like to see a successful conversion. If you have a highly tuned L36 or L67 it would be a BLAST to get on it hard and work your way through the gears. We wouldn't have to screw around with silly PCM shift points, torque converter issues, or half the stuff that plagues this maintenance forum. I think I'd be interested if it can be done effectively.
I think some of you are misunderstanding me, I'm running the plain old naturally aspirated 3.8, i'm not looking to tear up the neighborhood or burn the tires off of it, I just like rowing my own gears and having something that'* not very common...as far as deleting any data off the ecm...I've looked into a '95 Camaro/Firebird 5 speed 3.8 ecm with Prom...that should take care of that problem (I'm sure there will be more).
www.gmtuners.com may be able to help you out as well.
I would love a manuall.. If you need a dead pedal, i've seen blocks of wood cut up behind the carpet, with a gas pedal mounted to the front work nicely.

I know there is a way to trick your pcm into thinking it has shifted w/ leds or something.
I'm just waiting fro the new gm manual 6 speed to come out. Not that i've got the $ for something like that but those getrags have enough problems in old school grand prixs and fieros sometimes.

the Getrag 282 & 284 will mate up to the 3.8L engine but you'll need a custom flywheel. i swapped a Getrag 282 into my Cutlass and it was easy....the clutch pedal mount was already there since earlier W-bodies could be had with a manual transmission...installing the 5-speed shifter was also pure bolt-on.
just my opinion but i'd rather have an auto in my SSE than a 5-speed....i already have my Cutlass for that
that would be too cool
, I was thinking about that very same thing a few weeks ago, when I thought I had tranny probs, thats why I miss my old '89 Grand Prix, it had a 5spd getrag in it, and that car was close in size and wieght to a bonneville, but it only had a 2.8 in it...I dont know anyother full size fwd cars with 5spds in them though, I still have the fsm for that car, its in like 3 pieces
Theres not only the mechanical aspect that makes the project seem insurmountable, take into consideration that you will need to make room for a pedal assembly and the actual shifter assembly. I can imagine that the throw on the stick would resemble a Semi.
Yes it would be a neat thing to do though.
